Has anyone had any experience with synthetic grass flooring systems in pet relief areas? The previous posts about artificial turf focus on sports turf and there seem to be some Greenguard certified sports turf products but none appropriate for pet areas. Does anyone know of a pet relief grass product that has been tested against the California Department of Health Services Standard Practice for the Testing of Volatile Organic Emissions from Various Sources Using Small-Scale Environmental Chambers? Do the requirements of this credit even apply to these systems?
